FIRE-BRICK ARCH;

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed Febr uary 16, 1914. Serial No. 818,875.

Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fire-Brick Arches,-of

which the following is a specification.

This invention relates to fire brick arches of the kind which are installed' in fire boxes or boilers, and other like places, and designed to withstand the heat from and deflect the products of combustion.

The invention has for its object the construction and installation of a fire brick arch which can be put in old as well as new constructions; which can be installed by placing the tiles forming the same separately in position and "taken down by removal of said tile separately; and in case of the breaking of the elements of the arch can be repaired Without the removal of any considerable number of said elements. I

A further object is to obtain flexibility in the arch by providing means whereby horizontal and vertical movements of the elementsof-the arch are permitted.

In the drawings which accompany and form a part of this specification Figure 1 is a vertical section on line 11 of Fig. 2, viewed in the direction indicated by the arrows. Fig. 2 is a vertical section on line 22 of Fig. 1, viewed in the direction indi- Cated by the arrows. Fig. 3 is a vertical section, on line 33 of Fig. 4, of a' modification of the construction illustrated in Fi s. 1 and 2, viewed in the direction indicated y the arrows. Fig. 4 is a vertical section on line 4-4 of Fig. 3, viewed in the direction indicated by the arrows. Fig. 5 is a vertical section on line 2-2 of Fig. 1, on an enlarged scale, and viewed in the direction indicated by the arrows in said Fig. 1. Fig. 6

tion on line 10 -1O of Fig. 5, viewed in the direction indicated by the arrows.

A reference character applied to designate F. STEVENS,

a given part indicates said part throughout the several figures of the drawings, wherever the same appears.

A are the side walls of a fire box. B are U-shaped beams (channel beams), which are supported by the side walls A.

C, (Figs. 2, 4, 8' and 9) are I-beams.

B (Figs. 3 and 4), are curved U-shaped beams which are supported by the-side walls A, and are modifications of beams B.

D is an arch comprising the fire brick or tile (Z and the suspending devices cl, 0Z Fire brick or tile (Z- are respectively provided with the head d The sides of the fire brick or tile d are beveled, or on radial lines of the arch D, as shown. by lines (i Figs. 1 and 3;

' while the front and back faces thereof are substantially parallel, as shown by lines (i Figs. 2 and 4. 'Suspending devices (Z comprise the body member E provided with ratchet teeth 6 and heads e 6 Body member E is also provided with the slot 6 Said suspending device al also comprises the elastic members F and bolt f, with nut 7 Both ends of the elastic members Fare turned. The turning of the upper ends of said members provides means to engage said members F with the ratchet teeth 6 on members E; and the turning ofthe lower ends of said members provides means of engaging said members with the. under sides of the heads d of brick or tile 03. An adjustment of the members F on member E determines the vertical position, in the arch I); of the Member E is supported by the under side of the head 6 resting on the lower flange of the U-shaped pieces; and said under side, or face, of said head 6 curved to permit said head to rock on said flange. The incline desired in a given brick or tile is thus obtained. To insert the member al in place it is turned so that the longitudinal lines of bodies or heads 6 6 are at right angles with the side lines of the flanges on the U-shaped members, and said members E and F are then pushed or forced up between two of said U -shaped members, (which are placed in pairs). Said member d is then turned one quarter way around with heads e above and heads 6 below adjacent lower flanges of said U-shaped members. Heads 6 then support said member al and heads 6 prevent said member from being forced up.

The brick or tile supported by said member al is thereby held in its proper place in the arch, and can neither be forced above or drawn below its determined position. 'lihe proper incline of said brick or tile is obtainedby rocking the heads 6 on the flanges of the U-shaped members on' which they rest.

The suspending member 03 comprises the;

body member G provided with ratchet teeth 9; the elastic members H, bolt k, and the attaching member I. Attaching member I is provided with the hooked ends 2', 2', which are adapted to engage with the upper flange of an I l-beam, as is illustrated in Figs. 2, 4: and 9; and the upper ends of the elastic members H are turned out to rest on the sides of attaching members I when said elastic member is slid in between the parallel sides of said attaching member. The required incline of the brick or tile suspended on said member (2 to make said brick or tile fit in the arch, is obtained by slightly twisting attaching member 1!. Body member G is provided with a slot, corresponding,

to slot a in member E, and after engagement of the upper end of the elastic member H with the desired ones of the ratchet teeth 9', bolt is is secured in place. The lower end of the body member G is provided with the head J, and is engageable with the head on the tile or brick which is suspended thereby; and said head J is sufficiently long to permit said brick or tile to extend beyond the li-beam C, so that the additional tile or brick K may be placed on the upper side of the tiles forming the row under said Ill-beam, to protect said li-beam' from "the heated products of combustion flowing thereby.
